Release Time：2021-05-21
High-pressure gate valve, is the most widely used a valve, it is widely popular, is due to the opening and closing process between the tight cover friction is small, more durable, open height is not easy to manufacture, easy maintenance, not only suitable for low pressure, but also suitable for high pressure. Its closed principle is to rely on the valve bar pressure, so that the gate sealing surface and the valve seat sealing surface closely fit, to prevent the flow of media. High-pressure gate valve allows only one-way flow of medium, directional installation. Its structural length is greater than the gate valve, and the fluid resistance is large, and the sealing reliability is not strong during long-term operation.
Precautions for Installation and Maintenance of High Pressure Gate Valve
Handwheel, handle operated high pressure gate valve can be installed in any position of the pipeline.
Handwheel, handle and moving mechanism are not allowed to be used for lifting.
The flow direction of the medium should be consistent with the direction of the arrow shown in the valve body.

High-pressure gate valve allows only one-way flow of medium, directional installation. Its structural length is greater than the gate valve, and the fluid resistance is large, and the sealing reliability is not strong during long-term operation.
High-pressure gate valves are divided into three categories: straight-through, right-angle and straight-flow oblique gate valves.
The type of gate valve, according to the sealing surface configuration can be divided into wedge gate valve and parallel gate valve;
Wedge gate valve can be divided into: single gate pole type, double gate plate type and elastic gate type;
Parallel gate valve can be divided into single gate type and double gate plate type. According to the thread position of the valve stem, it can be divided into two kinds of open rod gate valve and dark rod gate valve.
